Method and apparatus for object tracking and detection
DC CAFCFirst Claim
1. A method for detecting a moving object of interest, having a characteristic with a predetermined value, in a field of view of a motion video camera using a video signal received from the motion video camera, said method comprising the steps of:
- receiving an object qualifying parameter representative of the characteristic with the predetermined value of the moving object of interest;
receiving an indication of a selected monitoring area in said field of view;
detecting moving objects within said selected monitoring area to determine the value of the characteristic of the moving object of interest for each detected moving object;
determining if a value of the characteristic for each detected moving object is within a predefined tolerance of the predetermined value of the moving object of interest; and
generating an indication of detected moving objects having the value of the characteristic within the predefined tolerance.

Abstract
A video image data reduction system through the use of object tracking reduces information in a video signal having a having a plurality of frames received from a motion video camera with a field of view. Moving objects in the field of view of the motion video camera are detected. These objects are selected if they are of interest. This is determined either by comparison of the detected object against predetermined characteristics of objects of interest or by manual user selection. A data set for each frame of the plurality of frames in the video signal is created based on the selected moving objects. If a frame contains no selected objects then the data set for that frame is marked as empty.
